Abstract
A field experiment was conducted at Agronomy farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar, Srinagar during 2008-2009 and 2009-10 on silty clay loam soil with neutral PH. The experiment comprising of three factors viz., cropping sequences S1 , S2, S3 and S4, three farm yard manure (FYM) rates R1 , R2 and R3 and three frequencies F1, F2 and F3 was laid out in a split plot design (cropping sequences in main plot and FYM rates and frequencies in sub plot) replicated thrice. The results showed that during 2009-10, the cropping sequences S1 and S4 recorded significantly higher growth characters, yield attributes and yield of maize than S2 and S3. the FYM rates increased the growth characters up to 30t ha⻹ and yield attributes up to 20t ha⻹. the grain yield of maize showed significant improvement with FYM application up to 20t ha⻹ while stover yield increased significantly up to 30 t ha⻹ FYM frequencies F1 and F2 recorded significantly higher growth characters, yield attributes and grain and stover yield of maize over F3. Highest net returns and benefit cost ratio were realized from the treatment combination S2R1F1. Key words: Maize, cropping sequence, farm yard manure (FYM), frequency
Highlights
Maize is one of the most important cereal crops grown all over the globe and has relatively higher production potential, wider adaptability and multifarious uses
The results showed that during 2009-10, the cropping sequences S1 and S4 recorded significantly higher growth characters, yield attributes and yield of maize than S2 and S3. the farm yard manure (FYM) rates increased the growth characters up to 30t ha−1 and yield attributes up to 20t ha−1. the grain yield of maize showed significant improvement with FYM application up to 20t ha−1 while stover yield increased significantly up to 30 t ha−1 FYM frequencies F1 and F2 recorded significantly higher growth characters, yield attributes and grain and stover yield of maize over F3
Maize was sown on 15th of May and 23rd of May during 2008-2009 and 2009-2010, respectively while lentil, oats, brown sarson were sown on 27th of April during both the seasons, Well decomposed FYM was applied as per the treatments for maize and half dose of nitrogen (45 Kg N ha1) and full doses of phosphorus (60 kg P ha1), potassium (40 kg K2O ha1) and Zinc (20 kg Zn ha1) was applied uniformly to each plot through urea, diammonium phosphate, muriate of potash and Zinc sulphate, respectively, In case of lentil whole recommended dose of nitrogen (40 kg ha1), phosphorus (60 kg ha1) and potassium (20 kg ha1) was band placed just before sowing
Summary
Maize is one of the most important cereal crops grown all over the globe and has relatively higher production potential, wider adaptability and multifarious uses. In J & k state maize is followed by rabi crops such as oats, brown sarson, pulses, berseem etc.; Lentil in the maize based cropping system can maintain soil fertility and sustain crop productivity, but keeping in view the need for providing nutritious fodder for increased livestock population and the need for edible oil for domestic consumption, maize- oats, maize- brown sarson cropping system have gained much popularity amongst the farming community Such a scenario demands addition of plant nutrients to soil in excess than their removal by the cropping system, maintaining the soil health. The present study entitled “Growth, Yield and Economics under maize (Zea mays L) based cropping system as influenced by rate and frequency of FYM’’ was undertaken
