Effect of different levels of organic and inorganic nutrient sources on growth and yield of mustard (Brassica juncea L.)

An experiment was conducted to study the effect of mulch (non-mulch and straw mulch) and different levels of nitrogen (0, 40, 80 and 120 kg ha-1) and potassium (0, 37.5, 75 and 112.5 kg ha-1) on the growth and yield of onion. Plants grown with straw mulch gave higher bulb yield (10.89 t ha-1) which showed 13.79% increase over non-mulch. Nitrogen increased the bulb yield significantly.The highest nitrogen level gave the highest bulb yield (12.13 t ha-1), which was 41.54% increase over control. Potassium increased bulb yield compared to control, but its different levels had identical results on yield. Nitrogen and mulch together produced significant variations. The Nitrogen at the highest level (120 kg ha-1) along with straw mulch gave the highest yield (13.31 t ha-1). Potassium together with mulch also exhibited significant variation on yield and yield components. Plants grown with the highest level of potassium (112.5 kg ha-1) along with straw mulch gave the highest bulb yield (11.58 t ha-1). Nitrogen and potassium as 120 kg N ha-1 × 75.0 kg K ha-1 gave the highest bulb yield (13.07 t ha-1). Nitrogen and potassium at their maximum levels with straw mulch gave the highest bulb yield (14.67 t ha-1).DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16747 Progress. Agric. 21(1 & 2): 39 - 46, 2010

Plot Design

A field experiment was conducted in the Experimental Research Farm of School of Agricultural Sciences and Rural Development (SASRD), Nagaland University during the kharif season 2018. Groundnut variety ICGS-76 was sown @ 70 kg ha-1 for 60×20 cm2 spacing. The experiment was laid in split plot design with three replications. The main plot treatments consisted of two lime levels: lime @ 0 t ha-1 and lime @ 3 t ha-1 while the sub- plot treatments consisted of five sulphur levels: sulphur @ (0 kg ha-1, 10 kg ha-1, 20 kg ha-1, 30 kg ha-1 and 40 kg ha-1 along with recommended dose of fertilizer at 20:60:40 kg N, P2O5 and K2O ha-1 respectively in the form of diammonium phosphate and murate of potash. The results showed that application of lime @ 3 t ha-1 gave higher growth and yield attributes compared to no lime and also application of sulphur @ 40 kg ha-1 gave higher growth and yield attributes compared to lower doses of sulphur though there was only slight increase in the attributes between each successive doses of sulphur. Overall application of lime and sulphur increased all the yield attributes of groundnut, where the highest number of pods plant-1, seeds pod-1, 100 kernels weight, pod yield, kernel yield and stover yield were recorded when treatment was done with lime @ 3 t ha1 and sulphur @ 40 kg ha-1.
