Background: Among pulses, blackgram is one of most important crop. Blackgram has originated from Indian sub-continent where it has been cultivated from ancient times and standout amongst most expensive pulse crop in India. Being observed, the productivity of blackgram is low in India as well as in Punjab due to lack of knowledge regarding various agronomic implementations, among them, time of sowing and selection of suitable cultivar are one of the major limiting factors in production, especially during kharif season. Methods: The research was carried out to investigate the effect of different dates of sowing on growth, yield attributes and yield of various cultivars of kharif blackgram (Vigna mungo L.) during kharif season 2019 at Student’s Research Farm, Department of Agriculture, Khalsa College, Amritsar. The experiment was laid-out in split-plot design, consisting of four dates of sowing (8th July, 18th July, 28th July and 8th August) as main-plot treatments and three cultivars (Mash114, Mash 338 and KUG 479) as sub-plot treatments, with four replications. Result: Among the sowing dates, the higher seed yield (10.27 q/ha) of blackgram was recorded when crop was raised on 8th July, which was significantly 12.6%, 20.3% and 30.5% higher than 18th July, 28th July and 8th August sown crop respectively. Among blackgram cultivars, the higher seed yield was observed in Mash 114 (10.19 q/ha) which was significantly 14% and 32% superior over Mash 338 and KUG 479 respectively. The sowing dates and cultivars had significant effect on the pods/plant, seeds/pod and seed weight/plant. The significantly higher number of pods/plant (24.3), seeds/pod (6.8) and seed weight/plant (3.2 g) were obtained with 8th July sown crop as compared to 28th July and 8th August sown crop. Among the cultivars, the significantly higher number of pods/plant (23.6), seeds/pod (6.4) and seed weight/plant (3.2 g) were recorded with Mash 114. The growth parameters viz. Plant height, nodules/plant, leaf area index and dry matter accumulation, were shown decreased trend by 29.2%, 19.13%, 12.2% and 25.4% respectively with the delay in sowing from 8th July to 8th August.

Background: Canola is an important oilseed crop throughout the world which is grown in more than 53 countries. Proper nutrient management plays a key role in its production. Use of unbalanced and inadequate fertilizers accompanied by restricted use of organic manures resulting in a decline in crop yield and quality. Little information is available on the response of canola to these factors. Therefore, this study is focused on to evaluate effect of foliar application of sulphur and integrated nutrient management on canola.Methods: A field experiment was conducted on sandy loam soil during winter (Rabi) season of 2017-18 and 2018-19 at Student’s Research Farm, Khalsa college, Amritsar to study the effect of foliar application of sulphur and integrated nutrient management on yield, quality and economics of bed transplanted canola (Brassica napus L.). Canola variety GSC 7 was sown by transplanting method on beds at spacing of 30 cm × 10 cm under Randomized Complete Block Design (RCBD) with 6 treatment combinations of organic (Vermicompost and pressmud), inorganic and foliar fertilizer were used under three replications. Result: The results revealed that treatment containing 100% RDF + 40 kgha-1 sulphur + 1% foliar sulphur spray (T2) led to maximum siliqua length (8.5 cm), no. of siliqua plant-1 (547.5), no. of seed siliqua-1 (28.8), test weight (4.64 g), seed yield (24.92 q ha-1) and stover yield (78.53 q ha-1) whereas treatment consisting 100% N through vermicompost + 40 kgha-1 sulphur + 1% foliar sulphur spray (T3) led to highest quality attributes i.e. oil content (43.73%), protein content (30.8%) in seed which was at par with 100% N through pressmud + 40 kgha-1 S + 1% foliar sulphur spray (T4) which also resulted highest sulphur content (0.48%) in seed. The maximum gross return (Rs. 104664 ha-1), net return (Rs. 59049 ha-1) and benefit cost rato (1.29) obtained from treatment containing 100% RDF + 40 kgh-1 sulphur + 1% foliar sulphur spray (T2). It was observed that foliar application of sulphur enhanced the yield whereas application of organic manures improved the quality of canola.

Information on the effect of combined use of chemical fertilizers and organic manures in Malt Barley is limited. Also, the effect of incorporation of rice straw on growth and yield of Malt Barley and use of the fungus Trichoderma viride for acceleration of decomposition of rice straw has not been studied much. Therefore, this present investigation entitled, “Effect of integrated nutrient management on productivity and quality of malt barley (Hordeum distichon L.)” was carried out during the rabi season of 2017-18 at Amritsar, Punjab, India. Treatments comprised of T1: Control, T2: 100% Inorganic fertilizers (IF), T3: 100% Farmyard manure (FYM), T4: 100% Chopped rice straw (CRS), T5: 100% CRS + Trichoderma viride (TV), T6: 75% IF + 25% FYM, T7: 50% IF + 50% FYM, T8: 75% IF + 25% CRS, T9: 50% IF + 50% CRS, T10: 75% IF + 25% CRS + TV, T11: 50% IF + 50% CRS + TV. Application of 100% NPK through inorganic fertilizers (IF) increased the ear length (7.92 cm), number of grains/ear (28.3), grain yield (44.6 q/ha) and straw yield (64.6 q/ha) and at par with 75% NPK through IF + 25% N through FYM. For a sustainable agriculture practice, up to 25% inorganic fertilizers can be substituted by FYM with less yield compensation. Furthermore, the soil pH, electrical conductivity and organic carbon content in the soil did not exhibit much affect in this single year trial. However, 100% NPK through IF significantly increased available N content over control and it was at par with 75% NPK through inorganic fertilizers + 25% N through FYM.

A field experiment was conducted during Rabi season of 2015-16 at the Students’ Research Farm, Khalsa College Amritsar, on sandy loam soil, low in organic carbon and available N, Medium in available P and high in available K. Field experiment was laid out in split plot design comprising four methods of sowing such as (Bed Planting, Zero tillage, Flat drilling, Happy seeder) and two row orientation as (North-South and East-West) replicated four times. Bed planting method produced significantly higher growth characters (i.e. plant height, leaf area index and dry matter accumulation, yield contributing characters effective tillers, grains ear-1, grain and straw yield, harvest index and B C ratio) than happy seeder and zero tillage sowing Bed planting recorded 14% and 10.48% higher grain yield over happy seeder and zero tillage sowing, respectively. Between row orientations, north-south row orientation produced higher growth and yield attributes than east-west whereas grain yield and biological yield was 3.86% and 3.77% higher than east-west sowing direction respectively.
