Yield quality parameters of rice-wheat system in response to integrated nutrient management over 31 years

Studies on the influence of Integrated Nutrient Management were undertaken during Rabi season, 2018-19 at College of Horticulture, Venkataramannagudem, West Godavari District, Andhra Pradesh with an objective of examining their influence on quality and yield of Strawberry fruits (Fragaria × ananassaDuch.) cv. Camarosa grown under shade net conditions. The experiment was consisting of 9 treatments replicated thrice comprising of different combinations of inorganic fertilizers, organic manures like FYM, vermicompost and biofertilizers like Arka microbial consortium in randomized block design. Observations were recorded for fruit yield and quality parameters. Among different combinations 75 % RDN + 25% N through Vermicompost + Arka Microbial Consortium registered highest number of fruits plant-1 (24.00), fruit diameter (3.18 cm) , fruit weight (13.40 g), fruit volume(21.24 cm3), fruit yield plant-1 (292.54 g), shelf life (44.10 h), juice recovery percentage (91.10 %) , TSS (11.05 °B), total sugars (7.71%), ascorbic acid (69.20 mg/100 g of pulp) and anthocyanin content (62.30 mg100g-1).

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.
