Thesis title : “Effect of nutrient management and irrigation scheduling on performance of Indian mustard (Brassica Juncea L.)
Oilseed crop has been the backbone agriculture economy of India from time immemorial. Amongst the various oilseeds, rapeseed and mustard (Brassica Spp.) are the third most important oilseed crop after groundnut and soya been in India occupying 6.18 Mha acreage, 7.36 Mt production and 1109 kg hectare productivity. In India Brassica Species are mostly grown in North India Region Consisting of Rajasthan, Uttar Pradesh, Parts of Madhya Pradesh, Gujarat, Punjab, Haryana Part of Himanchal Pradesh and are adopted to varies agro-climatic condition. Mustard is also called as raj raya or Laha it is supposed to be native of India. Among India Sates, Rajasthan First Ranks First Both Area and production of mustard with 2.33 Mt and 2.70 Mt respectively it is followed the state of Uttar Pradesh where mustard is grown on 12.95 lakh/ha with 8.00 lakh ton seed production and 730. Kg /ha productivity. However, Gujrat states highest productivity of mustard (1510 kg/ha) in the country. Upadhyay et al. (2018).
A field experiment was conducted during 2020-21 at Crop Research Center. Sardar Vallabhbhai Patel University of Agriculture and technology, Meerut (U.P.) to evaluate the Effect of nutrient management and irrigation scheduling on performance of Indian mustard (Brassica Juncea L.) The was laid out in split design with three replications. The rabi season experiment comprised of five levels of irrigation scheduling Growth stage (I1) Pre flowering stage (I2) Growth + siliqua stage (I3) Pre – flowering + siliqua stage (I4) Growth + Pre- flowering + siliqua (I5). and five level of nutrient management viz; Control (N1) RDF (120:60:40:40) (N2) RDF + Zn + B (N3) 75% RDF + 6 tonne (FYM) 25% (N4) 75% RDF + 6 tonne (FYM) + Zn + B (N5). The plant hight varied significantly due to different irrigation scheduling and nutrient management. the maximum plant hight was recorded in. Growth + Pre- flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) at all the stage of crop growth, while the minimum plant hight was observed with the application of Growth stage (I1) and Control (N1) at all the growth stage. Yield attributing characters like length of siliqua-1, number of siliqua -1 , seed siliqua-1, and 1000- seed weight exhibited variations due to different irrigation scheduling and nutrient management. With the application of Growth + Pre- flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) highest mean length of siliqua -1, number of siliqua -1 , seed siliqua-1, and 1000- seed weight was recorded. The highest seed yield, stover yield and biological yield was recorded in Growth + Pre- flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) and the lowest seed yield, stover yield and biological yield was recorded in Growth stage (I1) and Control (N1) . protein content also varied significantly due to different irrigation scheduling and nutrient management . the maximum protein content was found in Growth + Pre- flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) and minimum protein content was found in Growth stage (I1) and Control (N1) . nutrient content and their uptake by mustard seed and stover was influenced significantly due to irrigation scheduling and nutrient. Maximum and minimum nutrient content and their uptake were recorded with Growth + Pre- flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) and Growth stage (I1) and Control (N1) , respectively. the oil content varied significantly under different treatments. The maximum oil content was found with the application of Growth + Pre- flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) treatments. The minimum oil content was found in Growth stage (I1) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) . gross income and net profit were found significantly higher with the combination application of Growth + Pre- flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5)( Rs. 108318 and Rs. 82688), respectively over rest of treatment benefit : cost ratio was significantly affected by application of Growth + Pre- flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) alone with mean value 2.53 followed by remaining treatments. Thus , it may be concluded that application of Growth + Pre-flowering + siliqua (I5) and 75% RDF + 6 tonne (FYM) + Zn + B (N5) treatment , stage seems to best option for achieving higher yield and net returns from mustard crop.
