ThesisItem Open Access Effect of various nutrient sources on wheat in pearlmillet-wheat cropping system(CCSHAU, 2014) Babli; Pawan KumarA field experiment entitled ''Effect of various nutrient sources on wheat in pearlmillet-wheat cropping system'' was conducted during the year 2013-14 at Agronomy Research Farm of CCS Haryana Agricultural University, Hisar (India). The experiment consisting of twelve treatments was laid out in randomized block design with three replications. Grain yield of pearlmillet was recorded highest in T6 (50% RD-NP + 50% N through FYM). Yield contributing characters were recorded highest in T6 (50% RDNP + 50% N through FYM in pearlmillet and 100% RD-NP in wheat) in wheat crop. Grain, straw and biological yield of pearlmillet increased with increase in inorganic fertilizer dose. In wheat crop, treatment T6 recorded highest growth characters and yield contributing characters. Similarly, Highest grain, straw as well as biological yield was recorded in T6. Highest protein content as well as protein yield was also recorded in T6. Highest grain yield of both pearlmillet and wheat in pearl millet-wheat cropping system was obtained with the application of 50% RD-NP + 50% N through FYM in pearlmillet and 100% RD-NP in wheat. Highest net returns were obtained in T6 where 50% N in pearlmillet was supplied through FYM.ThesisItem Open Access Studies on productivity and carbon sequestration under integrated nutrient management in pearlmillet-wheat cropping system(CCSHAU, 2018) Babli; Pawan KumarA field experiment entitled "Studies on productivity and Carbon Sequestration under integrated nutrient management in pearlmillet-wheat cropping system" was conducted during the year 2015-16 and 2016-17 at Agronomy Research Farm of CCS Haryana Agricultural University, Hisar (India). The experiment consisting of twelve treatments was laid out in randomized block design with three replications. In pearlmillet crop, treatment T6 (50 % RD-NP + 50 % N through FYM in pearlmillet and 100 % RD-NPK in wheat) exhibited highest growth and yield contributing characters and was closely followed by T5. Highest grain yield of pearlmillet was recorded in treatment T6 where 50 % RD-NP + 50 % N through FYM in pearlmillet and 100 % RD-NP in wheat were applied. Grain, straw and biological yield of pearlmillet increased with progressive increase in plant nutrients through organic nutrient sources. Mean grain yield of pearlmillet was recorded highest in treatment T6 (3366 kg/ha). Among the chemical fertilizer treatments the grain, straw and biological yield increased with increasing dose of inorganic fertilizers. In pearlmillet-wheat cropping sequence microbial counts in pearlmillet were found higher in integrated nutrient management treatments as compared to inorganic fertilizer treatments. Higher carbon sustainability index was recorded in pearlmillet crop during both the years of the experiment as compared to wheat In wheat crop, treatment T6 recorded highest growth, yield contributing characters during both the years of the study. Similarly, highest grain, straw as well as biological yield was recorded in treatment T6 during first and second year. Mean grain yield was recorded highest in treatment T6 (5688 kg/ha), followed by treatment T5 which was significantly superior over rest of the treatments. Treatment T6 recorded highest protein content, protein yield, sedimentation value and hectolitre weight during both the years. Diazotrophs and phosphorus solublizing bacterial counts and establishment were observed highest in treatment T6 where 50 % N was supplemented through FYM. Organic carbon was reported maximum in integrated nutrient management treatments. Organic carbon maintains the soil fertility and microbial population. Mean maximum net returns were obtained in treatment T6 closely followed by T5 in pearl millet-wheat cropping sequence. Total carbon output and sustainability index were recorded maximum in wheat during both the years of the experiment.
