Determinants of smallholder membership in farmers’ groups in the pigeon pea-based farming system in Uganda

BackgroundMembership in farmers’ group (FGs) is an important social aspect of agricultural development. Little is known about the relative importance and benefits from participation in FGs in Uganda, specifically for pigeon pea smallholders in northern Uganda.MethodsWe conducted a cross-sectional survey with 257 smallholders to examine the factors that motivate farmer’s group membership and its influence on pigeon pea yield and technical efficiency (TE) in northern Uganda. We applied the Stochastic Production Frontier (SPF) model and complementary models to assess membership impact on pigeon pea yield and TE determinants, respectively. TE is defined as the degree to which smallholders use the minimum feasible farm inputs to produce a given level of pigeon pea grain.ResultsResults show that FG members were generally older and more experienced, and had better access to extension services (76%) and credit (43%) compared to non-members. Smallholders’ age, access to agricultural training, extension services, and the distance travelled to market centres were statistically significant (p < 0.05), thus limiting the likelihood of FG membership. TE for both groups was low and quite similar, at 63% and 59% for members and non-members, respectively, implying that both groups did not use the available farm resources to maximize pigeon pea yield.ConclusionOur results confirm that FG membership enhances smallholder’s access to extension, agricultural training services and credit. For northern Uganda, the study provides recommendations for increased government investment in the human, financial and physical capacity of extension agents as a strategy for rural development and improved livelihoods. In addition, policy incentives can encourage farmers to seek membership in farmers’ groups and related associations.

Enhancing agricultural output: Investigating the impact of advanced organic formulations on crop productivity, nutrient use efficiency, and profitability in a multi-crop system

The significance of integrating agricultural by-products such as paddy husk ash (PHA) and potato peels with organic fertilizers lies in enhancing soil fertility, increasing crop yields, and reducing reliance on traditional organic fertilizers like farmyard manure (FYM) or compost alone. Grounded in sustainable agriculture and nutrient management frameworks, this study examines the impact of diverse formulations derived from agricultural waste on productivity, nutrient efficiency, and profitability in a pigeon pea–vegetable mustard–okra cropping system. A two-year field experiment (2020–2022) at ICAR-IARI, New Delhi tested seven nutrient sources viz., (T1) control, (T2) 100% RDN through FYM, (T3) 100% RDN through improved RRC, (T4) 100% RDN through PHA based formulation, (T5) 75% RDN through PHA based formulation, (T6) 100% RDN through PPC based formulation and (T7) 75% RDN through PPC based formulation that were tested in RBD and replicated thrice. Treatment T4 had significant effect on seed yield of pigeon pea (1.89 ± 0.09 and 1.97 ± 0.12 t ha−1), leaf yield of vegetable mustard (81.57 ± 4.59 and 82.97 ± 4.17 t ha−1), and fruit yield of okra (13.54 ± 0.82 and 13.78 ± 0.81 t ha−1) grown in rotation, followed by treatment T6 and T2 during both the years respectively over control. Enhanced system uptake of N, P and K along with system gross and net returns in T4, showed increases of 78.9%, 83.8%, 72.4%, 54.4% and 56.8% in the first year and 77.5%, 80.8%, 77.7%, 54.8% and 57.4% in the second year, respectively, over control. Treatment T4 significantly improved apparent recovery by 66.3% and 69.2% in pigeon pea, 64.7% and 47.9% in vegetable mustard, and 72.7% and 79.4% in okra over T3, averaged across two years. Based on the above findings, (T4) 100% RDN through PHA-based formulation, and (T6) 100% RDN through PPC-based formulation can be recommended for areas with a shortage of FYM but availability of rice husk ash/potato peels for sustainable agricultural wastes and improved sustainability.

Optimizing agricultural sustainability: enriched organic formulations for growth, yield, and soil quality in a multi-crop system.

Utilizing agricultural and industrial wastes, potent reservoirs of nutrients, for nourishing the soil and crops through composting embodies a sustainable approach to waste management and organic agriculture. To investigate this, a 2-year field experiment was conducted at ICAR-IARI, New Delhi, focusing on a pigeon pea-vegetable mustard-okra cropping system. Seven nutrient sources were tested, including a control (T1), 100% recommended dose of nitrogen (RDN) through farmyard manure (T2), 100% RDN through improved rice residue compost (T3), 100% RDN through a paddy husk ash (PHA)-based formulation (T4), 75% RDN through PHA-based formulation (T5), 100% RDN through a potato peel compost (PPC)-based formulation (T6), and 75% RDN through PPC-based formulation (T7). Employing a randomized block design with three replications, the results revealed that treatment T4 exhibited the significantly highest seed (1.89 ± 0.09 and 1.97 ± 0.12 t ha-1) and stover (7.83 ± 0.41 and 8.03 ± 0.58 t ha-1) yield of pigeon pea, leaf yield (81.57 ± 4.69 and 82.97 ± 4.17 t ha-1) of vegetable mustard, and fruit (13.54 ± 0.82 and 13.78 ± 0.81 t ha-1) and stover (21.64 ± 1.31 and 22.03 ± 1.30 t ha-1) yield of okra during both study years compared to the control (T1). Treatment T4 was on par with T2 and T6 for seed and stover yield in pigeon pea, as well as okra, and leaf yield in vegetable mustard over both years. Moreover, T4 demonstrated notable increase of 124.1% and 158.2% in NH4-N and NO3-N levels in the soil, respectively, over the control. The enhanced status of available nitrogen (N) and phosphorus (P) in the soil, coupled with increased soil organic carbon (0.41%), total bacteria population (21.1%), fungi (37.2%), actinomycetes (44.6%), and microbial biomass carbon (28.5%), further emphasized the positive impact of T4 compared to the control. Treatments T2 and T6 exhibited comparable outcomes to T4 concerning changes in available N, P, soil organic carbon, total bacteria population, fungi, actinomycetes, and microbial biomass carbon. In conclusion, treatments T4 and T6 emerge as viable sources of organic fertilizer, particularly in regions confronting farmyard manure shortages. These formulations offer substantial advantages, including enhanced yield, soil quality improvement, and efficient fertilizer utilization, thus contributing significantly to sustainable agricultural practices.

Effect of Agronomic Biofortification of Zn and Fe on Growth, Yield and Economics of Pigeonpea

Pigeonpea (Cajanus cajan) is a major leguminous crop providing substantial nutritional benefits, especially protein to millions of people worldwide. However, its yield and nutritional quality are often constrained by micronutrient deficiencies, particularly zinc (Zn) and iron (Fe). This study investigates the effects of agronomic fortification with Zn and Fe on the growth, yield parameters and overall yield of pigeonpea. The experiment was conducted through a randomized complete block design with nine treatments and replicated thrice. Agronomic fortification involved foliar application of Zn and Fe at flowering and pod development stages. Results indicated that among different treatments the combined foliar application of 0.5 % ZnSO4 + 0.5 % FeSO4 at flower and pod initiation recorded significantly higher plant height (156.7 cm), number of branches per plant (16.8), number of pods per plant (98.5), number of seeds per pod (5.4), pod weight per plant (128.5 g), seed weight per plant (83.5 g), seed yield (1056 kg ha-1) and stalk yield (2503 kg ha-1) in the fortified treatments compared to the control. Notably, the combined Zn-Fe fortification exhibited the most pronounced effects on growth and yield parameters. Overall, agronomic fortification with Zn and Fe positively influenced the growth, yield parameters and yield of pigeonpea, suggesting its potential as a sustainable strategy to alleviate micronutrient deficiencies and enhance crop productivity in pigeonpea cultivation systems.

A field experiment was conducted during the rainy (kharif) season of 2011–12 and 2012–13 at Tirhut College of Agriculture, Dholi, Bihar, to study the effect of nutrient management for enhancing productivity of pigeonpea [Cajanus cajan (L.) Millsp.]-based intercropping systems. Pigeonpea + turmeric (Curcuma longa L.) intercropping system, recorded significantly higher pigeonpea yield (2.00 t/ha), pigeonpea-equivalent yield (4.79 t/ha), fruiting efficiency (18.8%), water-use efficiency (6.1 kg grain/ha/mm), production efficiency (18.0 kg/ha/day) and net re turns ( 106.32 ×10/ha) than pigeonpea + maize (Zea mays L.) intercropping and sole pigeonpea. However, pigeonpea + turmeric recorded lower benefit: cost (B: C) ratio than sole pigeonpea. Significantly higher B: C ratio was recorded under pigeonpea + sesame (Sesamum indicum L.) (2.32) and pigeonpea + urdbean [Vigna mungo (L.) Hepper] (2.31) intercropping systems than pigeonpea + maize, pigeonpea + turmeric and sole pigeonpea. Pigeonpea + maize recorded significantly lower NPK uptake by pigeonpea than sole pigeonpea and the other in tercropping systems. Pigeonpea + mungbean [Vigna radiata (L.) R. Wilczek] and pigeonpea + urdbean recorded significantly higher number and dry weight of nodules /plant than pigeonpea + maize. Application of 125% recom mended dose of fertilizer (RDF) recorded significantly higher number of branches and pods/plant, pigeonpea equivalent yield (3.39 t/ha), land-equivalent ratio (1.87), production efficiency (12.8 kg/ha/day), net returns ( 80.83 ×103/ha), benefit: cost ratio (2.17) and NPK uptake by pigeonpea than RDF and 75% RDF. Pigeonpea equivalent yield in pigeonpea + urdbean, pigeonpea + mungbean and pigeonpea + sesame intercropping sys tems, increased significantly with the increasing levels of fertilizer up to RDF, and further increase in fertilizer level did not show significant effect on pigeonpea-equivalent yield. However, it increased significantly up to 125% RDF in pigeonpea + maize and pigeonpea + turmeric intercropping systems. Pigeonpea + urdbean and pigeonpea + mungbean increased organic carbon, available N, P, K content of the soil than the other intercropping systems and initial soil value.

In available nutrients, among planting geometry and intercropping systems highest total available nitrogen and phosphorous was recorded in T14: Sole vegetable soybean (318.62 and 107.20 kg/ha N &amp; P respectively) and higher total available potassium was recorded in T13: Sole field bean (321.40 kg/ha K respectively), compared to other treatments. The study concludes that the paired row pigeonpea with vegetable soybean at 120/60 cm x 30 cm yield and economics of the intercropping systems.

Effect of Foliar Nutrition on Growth and Yield of Pigeonpea [Cajanus cajan. (L.) Mill sp.

Pigeonpea is most important rainfed pulse crop of Karnataka. Yield of pigeonpea is fluctuating due to variation in climate causing flower drop and poor pod set. The field experiment was conducted to study growth and yield of pigeonpea as influenced by foliar nutrition. The experiment consisted of foliar application of two types of nutrients (19:19:19 and Pulse magic), two growth promoters (NAA, and N - Triacontanol) and their combinations at flowering and pod formation stages. The growth and yield attributes varied significantly and RDF + foliar application of 1% pulse magic at flowering and pod formation stage recorded significantly higher plant height (144.6 cm), number of branches (16.8 plant‑1), leaf area (3218 cm2 plant-1), total dry matter accumulation (135.5 g plant-1), absolute growth rate (0.812 g plant-1 day-1,), crop growth rate (5.19 g m-2 day-1) and relative growth rate (0.01 g g-1 day-1) as compared to control (122.2 cm, 12.9, 2421 cm2 plant-1, 89.4 g plant-1, 0.633 g plant-1 day-1, 4.24 g m-2 day-1 and 0.007 g g-1 day-1, respectively) at harvest. Higher seed yield (1590 kg ha-1), stalk yield (4308 kg ha-1) and harvest index (0.26) recorded with the application of RDF + foliar application of 1% pulse magic at flowering and pod formation stage and lower seed yield, stalk yield and harvest index (1104 kg ha-1, 3416 kg ha-1 and 0.23, respectively) was recorded with control treatment.

Pigeonpea Productivity and Soil Health as Influenced by Phosphorus Levels and AM Fungi under Different Planting Methods

A field experiment was conducted at ARS, Bheemarayarnagudi, Karnataka to study the effect of phosphorus graded levels and inoculation of arbuscular mycorrhizal (AM) fungi under different establishment techniques in pigeonpea during kharif season of three years (2010-13) in Upper Krishna Project command area of Karnataka. The treatment consists of phosphorus graded levels (0, 12.5, 25, 37.5 and 50kg ha-1) with inoculation VAM fungi under two establishment techniques (Transplanted and dibbled) with randomized block design. Three-year pooled data indicated that, Application of 50 kg P + VAM under transplanting technique recorded significantly higher pigeonpea yield (1510 kg ha-1) and it was on par with application 37.5 kg P + VAM under transplanting method over rest of the treatment. The economics and nutrient uptake also noticed similar trend. It proved that pigeonpea could be successfully transplanted in the UKP command area of Karnataka by applying 37.5 kg of phosphorus ha-1 in conjunction with VAM fungus inoculation. This boosted crop productivity, nutrient availability, and net returns.

Simultaneous selection for yield and stability in pigeonpea of north east plain zone of India

Yield improvement is the prime objective of any varietal development programs. Therefore, stability of the yield becomes an important criterion in pigeon pea because it is cultivated in rainfed conditions. For the varietal development program, multi-environment trials are conducted to advance the entries at different stages of the trial and in turn to release as varieties. Multi-environmental trials have generally significant genotype and genotype × environment interactions effect, and different univariate and multi-variate stability methods have been used to study the genotype × environment interactions. The present study comprises fourteen pigeon pea entries of the initial varietal trial that were evaluated at five locations viz. Varanasi, Dholi, Ranchi, Kanpur, and Araul representing the North East Plain Zone of All India Coordinated Research Project on pigeon pea program during Kharif 2020-21. The AMMI model is used for genotype × environment interactions investigation. The combined index Model -I and II were used based on the weighted average for stability and yield components at 50:50 in model-I and 20:80 in model-II respectively. Based on both the combined indices the entries IPA18-33 and IPA203 were recorded as highly stable high-yielding entries for future use.
