Abstract

To estimate the “Effect of row spacing and nitrogen levels on the growth and yield of tomato under walk-in polythene tunnel condition” an experiment was conducted at Sakhakot in collaboration with Agriculture Extension Department Dargai Malakand Agency, Khyber Pakhtunkhwa Pakistan in the year 2011-12 to find out optimum row spacing for obtaining maximum yield of tomato under walk-in polythene tunnel condition and optimize the nitrogen level for higher tomato production. Randomized Complete Block Design (RCBD) with split plot arrangement was used in the experiment, treatments were replicated three times. There were two factors i.e. different row spacing (60, 90, 120 cm) and nitrogen levels (0, 60, 100, 140 kg ha -1 ). Tomato cultivar “Sahil” was used for the experiment. More days to flowering (62.93), days to fruiting (85.44), plant height (264.73cm) and number of branches (58.89) was obtained when nitrogen was applied at 140 kg ha -1 , while maximum number of fruits kg -1 (12.89) was recorded in control plots. The maximum number of fruits plant -1 (61.56), average fruit weight plant -1 (3.19 kg), fruit weight picking -1 plot -1 (17.78 kg) and yield (28.33 tones ha -1 ) were obtained when nitrogen was applied at 100 kg ha 1 .Similarly in case of row spacing, higher days to flowering (52.03), days to fruiting (81.08), plant height (261.23cm) and number of branches (58.10) was obtained when plants were row spaced at 120 cm. More number of fruits kg -1 (11.58) was recorded from the plot, having 60 cm row spacing. The maximum number of fruits plant -1 (58.03), average fruit weight per plant (2.92 kg), fruit weight picking -1 plot -1 (16.89 kg) and yield (27.96 tones ha -1 ) were produced by the plots having 90 cm row spacing. Thus, it is concluded that Sahil cultivar treated with 100 kg N ha -1 row spaced

Highlights

Introduction family SolanaceaeThe LycoperesicumThe botanical name of tomato is genus an annual and short lived perennial (Lycopersicon esculentum), belongs to the herbaceous plant
Tomato has naturally occurring antioxidant such as ‘Lycopene’ a major carotenoid which plays an important role in scavenging free radicals and protect from heart diseases, arthritis and aging process [68] in the years (2000) and (1996) respectively, evaluated NP fertilizers rates highly influenced the fruit yield in tomato
Higher fruit yields of tomato can be obtained by applying optimum amount of NP fertilizers [10]

Summary

Soil preparation harmful insects feeding on the vegetable crop

Soil inside the tunnel was thoroughly and reduction in water stress from wind. In ploughed and leveled. Source of nitrogen used the importance of tomato the research was in the experiment was Urea Whereas nitrogen was applied to an optimum row spacing for obtaining the soil in split doses. First dose was supplied maximum yield of tomato under walk-in at transplantation time and other before polythene tunnel condition and to explore an flowering at ten days interval after optimum nitrogen level for higher tomato transplantation. An experiment entitled “effect of row phosphate (containing 18% of phosphorous) spacing and Nitrogen levels on the growth &. Before the yield of tomato under walk-in polythene application of other fertilizer, at depth of 15 tunnel condition” was conducted at Sakhakot cm to 30 cm, the soil samples were randomly in collaboration with Agriculture Extension collected from the experimental field and Department Dargai Malakand Agency, analyzed and analysis is shown in Table
