Effect of Different Planting Dates on Tuber Production in Dahlia (Dahlia variabilis L.) in Low Hill Conditions of Himachal Pradesh, India

The research, entitled " Effect of different planting dates on tuber production in dahlia (Dahlia variabilis L.) in low hill conditions of Himachal Pradesh" was carried out at RHRTS Dhaulakuan, Ponta Sahib (HP). The study aimed to investigate the impact of different planting dates on tuber production in five dahlia cultivars (Anarkali, Gargi, Giani Zail Singh, Matungini and Suryadev) in low hill. Three planting dates (September 15th, October 15th and November 15th) were chosen for evaluating vegetative parameters. Plant height (109.61 cm) and internodal length (10.34 cm) both were found to be optimal in the cultivar Suryadev. Furthermore, the cultivar Matungini exhibited the highest plant spread (42.72 cm). In terms of tuber production, Anarkali demonstrated superior performance in tuber weight (368.90 g), and tuber yield per plot (2.00 kg). Conversely, Matungini excelled in the number of tubers per plant (4.69), tuber length (13.24 cm) and tuber diameter (30.25 mm), while Giani Zail Singh showcased the best tuber diameter. The planting date of October 15th was identified as highly suitable for optimal tuber production across all parameters under low hill climatic conditions.

Effect of Different Planting Dates of Maize on Infestation of Stem Borer (Chilo partellus Swinhoe)

The studies were carried out at the School of Agricultural Sciences and Rural Development, Medziphema campus, Nagaland University during 2019. The experiment was laid out in a Split Plot Design (SPD) having three replications. The cultivars viz., Zarsi, Sipho, Ronimi, Khoi and HQPM-1 were sown on 3 different dates i.e., 6th March, 21st March and 5th April. Among the five cultivars used the local cultivar ‘Sipho’was found to be the most tolerant and performed better than the composite variety ‘HQPM-1’ and the different dates of sowing, 5th April was found to be the most successful with the least infestation by Chilo partellus. The maize sown on 21st March recorded the highest grain yield (4.12 t/ha). Among the four cultivars and one composite variety evaluated, the highest grain yield was recorded from cultivar Sipho with 4.13 t/ha, while the lowest from cultivar Ronimi with 3.11 t/ha.

Relationship between weather factors and planting dates with references to growth and yield of potato (Solanum tuberosum) varieties

A field experiment was conducted during the winter season of 2016–17 and 2017–18 at the research farm of the Department of Agricultural Meteorology, College of Agriculture, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana to quantify the effect of different planting dates on the growth and yield of potato (Solanum tuberosum L.) cultivars. The experiment comprised 12 treatment combinations involving 4 date of sowing, viz. D1 , 8 October; D2 , 22 October; D3 , 5 November and D4 , 15 November as main plot treatment and viz. 3 varieties V1 , ‘Kufri Bahar’, V2 , ‘Kufri Pushkar’ and V3 , ‘Kufri Surya’, as sub-plot treatment in a split-plot design, replicated 4 times. The maximum tuber yield was recorded in D2 (21.9 tonnes/ha) as compared to the other sowing dates and the lowest in D4 (16.5 tonnes/ha). Among the varieties, ‘Kufri Pushkar’ had a significantly higher tuber yield (23.2 tonnes/ha) than ‘Kufri Bahar’ (18.0 tonnes/ha) and ‘Kufri Surya’ (16.6 tonnes/ha) during the crop season. Plant height, dry matter accumulation and biological yield were positively correlated with wind speed, rainfall and rainy days. The number of leaves/plant and leaf-area index (LAI) was significantly, negatively correlated with maximum and minimum temperatures, whereas it showed significant positive correlations with wind speed. Evening relative humidity was also positively correlated with LAI and tuber yield of potatoes. However, improved cultivars along with ideal planting windows at micro-level identification were the best way to mitigate the challenges posed by the climate in potatoes in near future.

YIELD AND QUALITY OF SOME MAIZE HYBRIDS (ZEA MAYS L.) UNDER DIFFERENT PLANTING DATES

For optimal maize yield, selecting the appropriate planting date based on a region's climatic conditions is crucial.
 This is especially true when considering the varying needs of different maize hybrids. To better understand the
 relationship between planting dates and yield for various maize hybrids, a study was conducted in Jiroft during
 2018 and 2019. This research examined ten maize hybrids across three distinct planting dates.The findings
 revealed that delaying the planting date reduced yield components, SPAD, GDD, oil percentage, and overall oil
 yield.Interestingly, the amino acid content increased with delayed planting. Among the hybrids, the 703 variant
 achieved its peak grain yield on July 18. In contrast, the lowest yield was recorded on August 1, marking a
 substantial 30.07% reduction in grain yield. These results underscore the significance of timely planting in
 maximizing both the yield and quality attributes of maize hybrids.

A Case Study of Energy Balance of Castor Bean Cultivation in Iran

The production of biofuel from farm products has been promoted as a replacement for fossil fuels. Castor bean (Ricinus communis L.) is one of the best crops used to produce biodiesel. The first step toward the introduction and widespread cultivation of the crop is to investigate the energy balance and economic analysis for its production in the field. To do so, we studied the comparison of the energy balance sheet on three different planting dates and plant densities of Castor beans in the Urmia. All data, such as input and output, were converted to equal values of the consumed and produced energy, by using special formulas and indexes, after which the energy efficiency was calculated. The results of analysis of variance showed that the effect of different planting dates on energy output of biomass, grain, oil, protein yield, and their energy efficiency was significant. Energy efficiency of oil and protein yield was also affected by plant density per unit area. The interaction effect of planting date and plant density was also significant on biomass energy output and its efficiency, energy efficiency of oil, and protein yield. According to the results, in order to achieve maximum energy efficiency, it is suggested that the most desirable planting date is May 20 and the most suitable density of 16,000 plants per hectare in West Azerbaijan.

Spring planting favors yield of new Brazilian potato cultivar BRS F63 Camila

ABSTRACT The objective of this work was to evaluate the effect of different planting dates on the morphological variables and yield of new potato cultivars. The treatments were three cultivars (Agata, BRS Clara and BRS F63 Camila) and three planting date (October, December and February), carried out in two crop years (2014/15 and 2015/16). Total and marketable yields, average mass of total and marketable tubers, growth period, leaf area index, number and dry weight of the tubers were evaluated. The first planting date resulted in higher yield than the third date. Cultivar BRS F63 Camila was the one with highest yield in this first planting date (47.4 t ha-1), due to greater number of tubers produced in relation to the other cultivars and to higher average tuber weight (166 g tuber-1) in relation to Agata (113 g tuber-1). In the second planting date, no difference in yield was observed among cultivars. In the third planting date, BRS Clara was the cultivar with highest yield (21.3 t ha-1), due mainly to higher average weight of tubers (105 g tuber-1) in relation to Agata (49 g tuber-1), a fact favored by the higher leaf area index and longer growth period of BRS Clara. Depending on the planting date, one should choose the cultivar that results in maximum yield potential, since it is a plant management with low cost and high yield impact. For the second planting date, any of the studied cultivars can be used.

Effect of different planting dates on some plant growth traits of four hybrids of broccoli

The experiment was conducted at the Vegetable Field, Department of Horticulture, College of Agriculture, University of Karbala, Iraq during 2017–18 for the evaluation of four cultivated hybrids with different planting dates and their consequence on some plant growth traits of broccoli. In this experiment, randomized complete block design (RCBD) was used with three replications. Four hybrids of broccoli (Ruby (V1), Green cornet (V2), Tropicana (V3) and Master (V4) were cultivated on three planting dates [September 15 (M1), October 01 (M2) and October 15 (M3), 2017]. The results indicated that the cultivar M4 produced significantly higher number of leaves as well as highest chlorophyll content in leaves, whereas cultivar V3 produced significantly more diameter and perimeter of the curd compared to other cultivars. Significantly higher plant height was recorded in the cultivar V2 compared to other cultivars. Among planting dates, broccoli planted on 1st October (M2) produced significantly higher diameter as well as perimeter of the curd compared to other planting dates V1 and V3. However, planting dates did not affect the other growth parameters of broccoli. The interaction between the effects of cultivars and planting dates was also found significant. The interaction treatment of V2 × M2 produced significantly higher plant height, chlorophyll content in leaves, curd weight and its’ diameter. The highest number of leaves and leaf area were recorded under interaction treatment of V4 × M1. On the basis of these results, it can be concluded that broccoli hybrids Tropicana (V3) and Master (V4) can be successfully cultivated in agroclimatic conditions of Iraq.

Field experiments were carried out at research farm of Department of Agricultural Meteorology, CCSHAU, Hisar during Rabi seasons of 2016-17 to quantify crop weather relationship and the effect of different planting dates on growth and yield of potato cultivars in a sub-tropical environment at Hisar. The experimental field was adjacent to Agro-meteorological observatory at 290 10' N latitude, 750 46' E longitude and altitude of 215.2 m. The main plots treatments consisted four date of sowing viz. D1- 8th Oct., D2-22th Oct., D3- 5th Nov. and D4- 23rd Nov. The sub-plots treatment consisted of three varieties (V1- Kufri Bahar, V2- Kufri Pushkar and V3- Kufri Surya). The forty eight treatment combinations were tested in split plot design with four replications. The results revealed that various growth and yield observations were recorded higher in second sown crop (22th Oct.) as followed by other planting dates. The maximum tuber yield were produced in D2 (20810.45 kg/ha) and it was least in D4 (14525.46 kg/ha). Among the varieties, Kufri Pushkar recorded highest tuber yield (21478.06 kg/ha) followed by Kufri Bahar (17432.26 kg/ha) and Kufri Surya (15378.11 kg/ha). In crop weather relationship, Tuber yield and plant height were significantly positively correlated with rainfall (0.80 and 0.92) and rainy days (0.50 and 0.53). Evening relative humidity was also positively correlated with LAI (0.59) and tuber yield (0.78) of potato. Vegetables production is considered to be particularly important in satisfying world food demand. Specific research therefore is needed in order to evaluate the effects of environmental factors that crop encounters during its growth period and its production.
